Ms T will sell a caliper recon kit if you'd like one from her - around £50 for the kit but it recons both calipers depending on the kit - a front kit will recon both fronts, the rear kit both rears.

There is pink (I think it's lithium based) grease in with the kit - which is the thing I used to lube it all up when it goes back together.

The kit contains replacement rubber boots for the slider pins, replacement piston/cylinder seal, replacement dust boot for the piston and a few other bits which may or may not be usefull.

Not sure of the official reason for not using copper grease but what I've seen where it was used on my Mk1 the heat seemed to cause the grease to run out of the stuff leaving stuff behind that amalgamated and turned in to a fairly hard black sludge that glued stuff together.

I've used the kit a few times on different cars (Tubby, Mk1 NA and Mk1 SC) and IMHO it's a top kit.

If you want to give this a try let me know - there are a few tricks to the job that make it easier.

Ok - I finally found the time to have a look at my front brakes. Took the calipers and pads off and cleaned everything up. The sliders moved after a small amount of pressure and seemed pretty free, so I didn't bother to take them apart.

I'm missing the anti-squeal slim & bottom support brackets as listed in the haynes manual, is this going to be a problem?

I'm not sure how to test too see if it's fixed the advised on MOT, other than going back to the garage and getting them to test it.

Thanks for all the advice, it was fairly straight forward.

Gary.
